Devil Bringer

Overview
The Devil Bringer is the "weapon" the takes the form of Nero's right arm. It's origins remain a mystery but it bestows upon Nero incredible power, including the ability to bend space and time to pull himself across distances instantly and pull enemies to Nero. It also gives him incredible strength, as he is able to stop Berial's (who is more than ten-times Nero's size) sword srike with his human arm. The story seems to focus some attention on the Devil Bringer, it's powers, and it's origins. It also seems to disturb Kyrie, the main female lead in the game, that Nero possesses the Devil Bringer, possibly because it is obviously of demonic origin.
